Title: Self-healing bidirectional logical-ring network using crossconnects
Inventor: SANDESARA NIRANJAN BHOGILAI
IPC: H04L12/42
Filed: 1992-02-06
Granted: 1999-01-12
Abstract: A bidirectional logical-ring network employs crossconnect nodes (1100 and 1200), which partition the network into segments (X, Y and Z) and interconnect segments at the subchannel level to form logical ring structures. All segments are independent, and each segment includes a subset of Add-Drop Multiplex nodes (ADM s) (300 through 800) and two pairs of links (E through P), one working and one protection. The formation of logical rings from the interconnection of independent segment subchannels preserves the self-healing advantages of conventional bidirectional ring networks and allows greater flexibility to efficiently accommodate bandwidth upgrade requests.

Abstract: L'invention concerne un procédé de traitement de la viande fraîche, en particulier de maturation et de conservation de la viande fraîche de boeuf, de porc, de veau, d'agneau, de gibier, de volaille, ainsi que des poissons, des saucisses et du jambon. Selon ledit procédé, la viande est stockée, pendant une durée prédéterminée, dans un espace (1) pouvant être hermétiquement fermé, dont l'atmosphère est différente de l'atmosphère extérieure. On crée une telle atmosphère tout d'abord en évacuant de l'espace hermétiquement fermé les gaz correspondant à l'atmosphère ambiante, par l'intermédiaire d'un orifice d'évacuation (13), puis en introduisant de l'oxygène par un orifice d'entrée (4), de façon que la pression de l'atmosphère d'oxygène soit supérieure à la pression atmosphérique. Pendant toute la fin de cette période de stockage, la pression intérieure de l'espace fermé hermétiquement est maintenue à un niveau supérieur à la pression atmosphérique. Cela améliore la tendreté de la viande, tout en lui conservant ses qualités et en lui conférant une fraîcheur durable. L'invention concerne également un dispositif permettant la mise en oeuvre dudit procédé.
